Scientists try new strategy to eradicate dengue fever.(1/2084)
(+info)Early immune activation in acute dengue illness is related to development of plasma leakage and disease severity. (2/2084)
T lymphocyte activation and increased cytokine levels have been described in retrospective studies of children presenting with dengue hemorrhagic fever (DHF). Serial plasma samples obtained in a prospective study of Thai children presenting with <72 h of fever were studied. Plasma levels of 80-kDa soluble tumor necrosis factor receptors (sTNFRs) were higher in children who developed DHF than in those with dengue fever (DF) or other nondengue febrile illnesses (OFIs) and were correlated with the degree of subsequent plasma leakage. Soluble CD8 and soluble interleukin-2 receptor levels were also elevated in children with DHF compared with those with DF. Interferon-gamma and sTNFR 60-kDa levels were higher in children with dengue than in those with OFIs. TNF-alpha was detectable more often in DHF than in DF or OFIs (P<.05). These results support the hypothesis that immune activation contributes to the pathogenesis of DHF. Further studies evaluating the predictive value of sTNFR80 for DHF are warranted. (+info)Variation in oral susceptibility to dengue type 2 virus of populations of Aedes aegypti from the islands of Tahiti and Moorea, French Polynesia. (3/2084)
Twenty three samples of Aedes aegypti populations from the islands of Tahiti and Moorea (French Polynesia) were tested for their oral susceptibility to dengue type 2 virus. The high infection rates obtained suggest that the artificial feeding protocol used was more efficient than those previously described. Statistical analysis of the results allowed us to define two distinct geographic areas on Tahiti with respect to the susceptibility of Ae. aegypti: the east coast, with homogeneous infection rates, and the west coast, with heterogeneous infection rates. No geographic differences could be demonstrated on Moorea. The possible mechanisms of this phenomenon are discussed in connection with recent findings on the variability of susceptibility of Ae. aegypti to insecticides. (+info)Serologic evidence for an epizootic dengue virus infecting toque macaques (Macaca sinica) at Polonnaruwa, Sri Lanka. (4/2084)
Dengue is one of the most rapidly emerging diseases in the tropics. Humans are the principal reservoir of dengue viruses. It is unclear if nonhuman primates also serve as a reservoir of human dengue viruses under certain conditions. In this study, a cross-sectional serologic survey was carried out to characterize the pattern of transmission of a recently identified dengue virus among toque macaques in Sri Lanka. The results indicated that an epizootic dengue virus was active among the macaques. A single epizootic had taken place between October 1986 and February 1987 during which 94% of the macaques within the 3 km2 study site were exposed to the virus. The epizootic was highly focal in nature because macaques living 5 km from the study population were not exposed to the virus. The transmission of dengue viruses among macaques in the wild may have important public health implications. (+info)Bacterial lipopolysaccharide inhibits dengue virus infection of primary human monocytes/macrophages by blockade of virus entry via a CD14-dependent mechanism. (5/2084)
Monocytes/macrophages (MO/Mphi) are the major target cells for both dengue virus (DV) and bacterial lipopolysaccharide (LPS), and the aim of this study was to define their interactions. We had found that LPS markedly suppressed DV infection of primary human MO/Mphi when it was added to cultures prior to or together with, but not after, viral adsorption. The inhibitory effect of LPS was direct and specific and was not mediated by LPS-induced secretion of cytokines and chemokines such as tumor necrosis factor alpha, interleukin-1beta (IL-1beta), IL-6, IL-8, IL-12, alpha interferon, MIP-1alpha, and RANTES. In fact, productive DV infection was not blocked but was just postponed by LPS, with a time lag equal to one viral replication cycle. Time course studies demonstrated that LPS was only effective in suppressing DV infection of MO/Mphi that had not been previously exposed to the virus. At various time points after viral adsorption, the level of unbound viruses that remained free in the culture supernatants of LPS-pretreated cultures was much higher than that of untreated controls. These observations suggest that the LPS-induced suppression of DV replication was at the level of virus attachment and/or entry. Blockade of the major LPS receptor, CD14, with monoclonal antibodies MY4 or MoS39 failed to inhibit DV infection but could totally abrogate the inhibitory effect of LPS. Moreover, human serum could significantly enhance the LPS-induced DV suppression in a CD14-dependent manner, indicating that the "binding" of LPS to CD14 was critical for the induction of virus inhibition. Taken together, our results suggest that LPS blocked DV entry into human MO/Mphi via its receptor CD14 and that a CD14-associated cell surface structure may be essential for the initiation of a DV infection. (+info)A deviation bar chart for detecting dengue outbreaks in Puerto Rico. (6/2084)
OBJECTIVES: A Centers for Disease Control and Prevention deviation bar chart (Statistical Software for Public Health Surveillance) and laboratory-based surveillance data were evaluated for their utility in detecting dengue outbreaks in Puerto Rico. METHODS: A significant increase in dengue incidence was defined as an excess of suspected cases of more than 2 SDs beyond the mean for all 4-week periods from April through June (the period of lowest seasonal incidence), 1989 through 1993. An outbreak was defined as a cumulative annual rate of reported dengue greater than 3 per 1000 population. RESULTS: Retrospective application of the system to 1994 data showed agreement with previous analyses. In 1995 and 1996, 36.4% and 27.3%, respectively, of municipalities with a significant increase in reports for 2 or more consecutive weeks before the first week of September had an outbreak, compared with 9.0% (in 1995, P = .042) and 6.0% (in 1996, P = .054) of towns without a significant increase. The system showed sensitivity near 40%, specificity near 89%, and accuracy in classifying municipalities near 84%. CONCLUSIONS: This method provides a statistically based, visually striking, specific, and timely signal for dengue control efforts. (+info)Effects of dengue fever during pregnancy in French Guiana. (7/2084)
To determine the effects of dengue fever (DF) during pregnancy, pregnant women presenting with a dengue-like syndrome at a hospital in Saint-Laurent du Maroni, French Guiana, from 1 January 1992 to 1 April 1998 were studied. The diagnosis of DF was made by serological tests, virus isolation on AP 61 mosquito cells, and/or reverse transcriptase polymerase chain reaction analysis. Twenty-two women had either probable or confirmed DF. Dengue virus serotype 2 was detected in four cases, and dengue virus serotype 1 was detected in one. Three fetuses died following the onset of the disease, and three cases of prematurity occurred. All infants appeared normal during physical examination, and no neonatal DF was diagnosed. In conclusion, DF in pregnant women did not cause any infant abnormality, but it may have been responsible for fetal death. The rate of fetal death associated with DF (13.6%) was much higher than the mean rate for the gynecology unit at the hospital (1.9%). However, these differences were not significant, and consequently these preliminary results need to be confirmed. (+info)Evaluation of the MRL diagnostics dengue fever virus IgM capture ELISA and the PanBio Rapid Immunochromatographic Test for diagnosis of dengue fever in Jamaica. (8/2084)
We evaluated two new commercial dengue diagnostic tests, the MRL Diagnostics Dengue Fever Virus IgM Capture ELISA and the PanBio Rapid Immunochromatographic Test, on serum samples collected during a dengue epidemic in Jamaica. The MRL ELISA method correctly identified 98% (78 of 80) of the samples as dengue positive, while the PanBio test identified 100% (80 of 80). Both tests were 100% (20 samples of 20) specific. (+info)Dengue is a mosquito-borne viral infection that is primarily transmitted by the Aedes aegypti and Aedes albopictus species of mosquitoes. It is caused by one of four closely related dengue viruses (DENV 1, DENV 2, DENV 3, or DENV 4). The infection can cause a wide range of symptoms, ranging from mild fever and headache to severe flu-like illness, which is often characterized by the sudden onset of high fever, severe headache, muscle and joint pain, nausea, vomiting, and skin rash. In some cases, dengue can progress to more severe forms, such as dengue hemorrhagic fever or dengue shock syndrome, which can be life-threatening if not treated promptly and appropriately.
Dengue is prevalent in many tropical and subtropical regions around the world, particularly in urban and semi-urban areas with poor sanitation and inadequate mosquito control. There is no specific treatment for dengue, and prevention efforts focus on reducing mosquito populations and avoiding mosquito bites. Vaccines are available in some countries to prevent dengue infection, but they are not widely used due to limitations in their effectiveness and safety.
Dengue virus (DENV) is a single-stranded, positive-sense RNA virus that belongs to the genus Flavivirus in the family Flaviviridae. It is primarily transmitted to humans through the bites of infected female mosquitoes, mainly Aedes aegypti and Aedes albopictus.
The DENV genome contains approximately 11,000 nucleotides and encodes three structural proteins (capsid, pre-membrane/membrane, and envelope) and seven non-structural proteins (NS1, NS2A, NS2B, NS3, NS4A, NS4B, and NS5). There are four distinct serotypes of DENV (DENV-1, DENV-2, DENV-3, and DENV-4), each of which can cause dengue fever, a mosquito-borne viral disease.
Infection with one serotype provides lifelong immunity against that particular serotype but only temporary and partial protection against the other three serotypes. Subsequent infections with different serotypes can increase the risk of developing severe dengue, such as dengue hemorrhagic fever or dengue shock syndrome, due to antibody-dependent enhancement (ADE) and original antigenic sin phenomena.
DENV is a significant public health concern in tropical and subtropical regions worldwide, with an estimated 390 million annual infections and approximately 100-400 million clinical cases. Preventive measures include vector control strategies to reduce mosquito populations and the development of effective vaccines against all four serotypes.
Severe dengue, also known as dengue hemorrhagic fever, is a severe and potentially fatal complication of dengue virus infection. The World Health Organization (WHO) defines it as follows:
"Dengue hemorrhagic fever is characterized by a high fever (40°C/104°F) that lasts for 2-7 days, with generalized pain and severe headache, bleeding manifestations (e.g., nose or gum bleed, skin rash with bruising, internal bleeding), plasma leakage leading to accumulation of fluid in the lungs or abdomen, and a rapid decrease in platelet count."
Severe dengue can be life-threatening if not diagnosed and treated promptly. It is important to seek medical attention immediately if you suspect you have dengue fever and are experiencing any of the symptoms associated with severe dengue.
Dengue vaccines are designed to protect against dengue fever, a mosquito-borne viral disease that can cause severe flu-like symptoms and potentially life-threatening complications. Dengue is caused by four distinct serotypes of the virus (DENV-1, DENV-2, DENV-3, and DENV-4), and infection with one serotype does not provide immunity against the others.
The first licensed dengue vaccine, Dengvaxia (CYD-TDV), is a chimeric yellow fever-dengue tetravalent vaccine developed by Sanofi Pasteur. It is approved for use in several countries and has demonstrated efficacy against dengue fever caused by all four serotypes in clinical trials. However, the vaccine has raised concerns about the risk of severe disease in individuals who have not been previously exposed to dengue. As a result, it is recommended primarily for people with a documented past dengue infection or living in areas with high dengue prevalence and where the benefits outweigh the risks.
Another dengue vaccine candidate, Takeda's TAK-003 (also known as TDV), is a live attenuated tetravalent dengue vaccine that has shown efficacy against all four serotypes in clinical trials. It was granted approval by the European Medicines Agency (EMA) and several other countries for use in individuals aged 4-16 years old, living in endemic areas.
Research and development of additional dengue vaccine candidates are ongoing to address concerns about safety, efficacy, and accessibility, particularly for at-risk populations in low- and middle-income countries where dengue is most prevalent.
"Aedes" is a genus of mosquitoes that are known to transmit various diseases, including Zika virus, dengue fever, chikungunya, and yellow fever. These mosquitoes are typically found in tropical and subtropical regions around the world. They are distinguished by their black and white striped legs and thorax. Aedes aegypti is the most common species associated with disease transmission, although other species such as Aedes albopictus can also transmit diseases. It's important to note that only female mosquitoes bite and feed on blood, while males feed solely on nectar and plant juices.
Insect vectors are insects that transmit disease-causing pathogens (such as viruses, bacteria, parasites) from one host to another. They do this while feeding on the host's blood or tissues. The insects themselves are not infected by the pathogen but act as mechanical carriers that pass it on during their bite. Examples of diseases spread by insect vectors include malaria (transmitted by mosquitoes), Lyme disease (transmitted by ticks), and plague (transmitted by fleas). Proper prevention measures, such as using insect repellent and reducing standing water where mosquitoes breed, can help reduce the risk of contracting these diseases.
Antibodies, viral are proteins produced by the immune system in response to an infection with a virus. These antibodies are capable of recognizing and binding to specific antigens on the surface of the virus, which helps to neutralize or destroy the virus and prevent its replication. Once produced, these antibodies can provide immunity against future infections with the same virus.
Viral antibodies are typically composed of four polypeptide chains - two heavy chains and two light chains - that are held together by disulfide bonds. The binding site for the antigen is located at the tip of the Y-shaped structure, formed by the variable regions of the heavy and light chains.
There are five classes of antibodies in humans: IgA, IgD, IgE, IgG, and IgM. Each class has a different function and is distributed differently throughout the body. For example, IgG is the most common type of antibody found in the bloodstream and provides long-term immunity against viruses, while IgA is found primarily in mucous membranes and helps to protect against respiratory and gastrointestinal infections.
In addition to their role in the immune response, viral antibodies can also be used as diagnostic tools to detect the presence of a specific virus in a patient's blood or other bodily fluids.
'Culicidae' is the biological family that includes all species of mosquitoes. It consists of three subfamilies: Anophelinae, Culicinae, and Toxorhynchitinae. Mosquitoes are small, midge-like flies that are known for their ability to transmit various diseases to humans and other animals, such as malaria, yellow fever, dengue fever, and Zika virus. The medical importance of Culicidae comes from the fact that only female mosquitoes require blood meals to lay eggs, and during this process, they can transmit pathogens between hosts.

Antibody-Dependent Enhancement (ADE) is a phenomenon in which the presence of antibodies against a particular virus actually enhances the ability of the virus to infect and replicate within host cells, leading to increased severity of infection. This occurs when the antibodies bind to the virus but do not neutralize it, instead facilitating uptake of the virus into immune cells expressing Fc receptors, such as macrophages. The virus can then use these cells as a site for replication and evasion of the host's immune response. ADE has been observed in various viral infections, including dengue fever and respiratory syncytial virus (RSV) infection. It is a concern in the development of vaccines against these viruses, as non-neutralizing antibodies induced by vaccination could potentially enhance subsequent infection with a heterologous strain of the virus.
Viral nonstructural proteins (NS) are viral proteins that are not part of the virion structure. They play various roles in the viral life cycle, such as replication of the viral genome, transcription, translation regulation, and modulation of the host cell environment to favor virus replication. These proteins are often produced in large quantities during infection and can manipulate or disrupt various cellular pathways to benefit the virus. They may also be involved in evasion of the host's immune response. The specific functions of viral nonstructural proteins vary depending on the type of virus.
A disease outbreak is defined as the occurrence of cases of a disease in excess of what would normally be expected in a given time and place. It may affect a small and localized group or a large number of people spread over a wide area, even internationally. An outbreak may be caused by a new agent, a change in the agent's virulence or host susceptibility, or an increase in the size or density of the host population.
Outbreaks can have significant public health and economic impacts, and require prompt investigation and control measures to prevent further spread of the disease. The investigation typically involves identifying the source of the outbreak, determining the mode of transmission, and implementing measures to interrupt the chain of infection. This may include vaccination, isolation or quarantine, and education of the public about the risks and prevention strategies.
Examples of disease outbreaks include foodborne illnesses linked to contaminated food or water, respiratory infections spread through coughing and sneezing, and mosquito-borne diseases such as Zika virus and West Nile virus. Outbreaks can also occur in healthcare settings, such as hospitals and nursing homes, where vulnerable populations may be at increased risk of infection.
I'm sorry for any confusion, but "Vietnam" is not a medical term. It is the name of a country located in Southeast Asia. If you have any questions about medical conditions or terminology, I would be happy to help clarify those for you.
Flavivirus is a genus of viruses in the family Flaviviridae. They are enveloped, single-stranded, positive-sense RNA viruses that are primarily transmitted by arthropod vectors such as mosquitoes and ticks. Many flaviviruses cause significant disease in humans, including dengue fever, yellow fever, Japanese encephalitis, West Nile fever, and Zika fever. The name "flavivirus" is derived from the Latin word for "yellow," referring to the yellow fever virus, which was one of the first members of this genus to be discovered.
'Mosquito Control' is not a medical term per se, but it is a public health concept that refers to the systematic reduction or elimination of mosquito populations through various methods to prevent or minimize the transmission of mosquito-borne diseases. This multidisciplinary field involves entomologists, ecologists, engineers, and public health professionals working together to manage mosquito habitats, apply insecticides, and educate communities about personal protection measures. By controlling mosquito populations, we can significantly reduce the risk of contracting vector-borne illnesses such as malaria, dengue fever, yellow fever, Zika virus, and West Nile virus, among others.
Serotyping is a laboratory technique used to classify microorganisms, such as bacteria and viruses, based on the specific antigens or proteins present on their surface. It involves treating the microorganism with different types of antibodies and observing which ones bind to its surface. Each distinct set of antigens corresponds to a specific serotype, allowing for precise identification and characterization of the microorganism. This technique is particularly useful in epidemiology, vaccine development, and infection control.
Immunoglobulin M (IgM) is a type of antibody that is primarily found in the blood and lymph fluid. It is the first antibody to be produced in response to an initial exposure to an antigen, making it an important part of the body's primary immune response. IgM antibodies are large molecules that are composed of five basic units, giving them a pentameric structure. They are primarily found on the surface of B cells as membrane-bound immunoglobulins (mlgM), where they function as receptors for antigens. Once an mlgM receptor binds to an antigen, it triggers the activation and differentiation of the B cell into a plasma cell that produces and secretes large amounts of soluble IgM antibodies.
IgM antibodies are particularly effective at agglutination (clumping) and complement activation, which makes them important in the early stages of an immune response to help clear pathogens from the bloodstream. However, they are not as stable or long-lived as other types of antibodies, such as IgG, and their levels tend to decline after the initial immune response has occurred.
In summary, Immunoglobulin M (IgM) is a type of antibody that plays a crucial role in the primary immune response to antigens by agglutination and complement activation. It is primarily found in the blood and lymph fluid, and it is produced by B cells after they are activated by an antigen.
I'm sorry for any confusion, but "Puerto Rico" is not a medical term. It is a territorial possession of the United States, located in the northeastern Caribbean Sea. It includes the main island of Puerto Rico and various smaller islands. If you have any questions about a medical topic, please provide more details so I can try to help answer your question.
A disease vector is a living organism that transmits infectious pathogens from one host to another. These vectors can include mosquitoes, ticks, fleas, and other arthropods that carry viruses, bacteria, parasites, or other disease-causing agents. The vector becomes infected with the pathogen after biting an infected host, and then transmits the infection to another host through its saliva or feces during a subsequent blood meal.
Disease vectors are of particular concern in public health because they can spread diseases rapidly and efficiently, often over large geographic areas. Controlling vector-borne diseases requires a multifaceted approach that includes reducing vector populations, preventing bites, and developing vaccines or treatments for the associated diseases.
I'm sorry for any confusion, but "travel" is not a term that has a specific medical definition. In general, travel refers to the act of moving or journeying from one place to another, often over long distances. However, in a medical context, it might refer to the recommendation that individuals with certain medical conditions or those who are immunocompromised avoid traveling to areas where they may be at increased risk of exposure to infectious diseases. It's always best to check with a healthcare professional for advice related to specific medical situations and travel.
I apologize, but "Brazil" is not a medical term or condition. It is the largest country in both South America and Latin America by land area and population. If you have any questions related to medical terminology or health concerns, please provide more information and I will do my best to help.
An Enzyme-Linked Immunosorbent Assay (ELISA) is a type of analytical biochemistry assay used to detect and quantify the presence of a substance, typically a protein or peptide, in a liquid sample. It takes its name from the enzyme-linked antibodies used in the assay.
In an ELISA, the sample is added to a well containing a surface that has been treated to capture the target substance. If the target substance is present in the sample, it will bind to the surface. Next, an enzyme-linked antibody specific to the target substance is added. This antibody will bind to the captured target substance if it is present. After washing away any unbound material, a substrate for the enzyme is added. If the enzyme is present due to its linkage to the antibody, it will catalyze a reaction that produces a detectable signal, such as a color change or fluorescence. The intensity of this signal is proportional to the amount of target substance present in the sample, allowing for quantification.
ELISAs are widely used in research and clinical settings to detect and measure various substances, including hormones, viruses, and bacteria. They offer high sensitivity, specificity, and reproducibility, making them a reliable choice for many applications.
A viral RNA (ribonucleic acid) is the genetic material found in certain types of viruses, as opposed to viruses that contain DNA (deoxyribonucleic acid). These viruses are known as RNA viruses. The RNA can be single-stranded or double-stranded and can exist as several different forms, such as positive-sense, negative-sense, or ambisense RNA. Upon infecting a host cell, the viral RNA uses the host's cellular machinery to translate the genetic information into proteins, leading to the production of new virus particles and the continuation of the viral life cycle. Examples of human diseases caused by RNA viruses include influenza, COVID-19 (SARS-CoV-2), hepatitis C, and polio.
The "Americas" is a term used to refer to the combined landmasses of North America and South America, which are separated by the Isthmus of Panama. The Americas also include numerous islands in the Caribbean Sea, Atlantic Ocean, and Pacific Ocean. This region is home to a diverse range of cultures, ecosystems, and historical sites. It is named after the Italian explorer Amerigo Vespucci, who was one of the first Europeans to explore and map parts of South America in the late 15th century.
Viral envelope proteins are structural proteins found in the envelope that surrounds many types of viruses. These proteins play a crucial role in the virus's life cycle, including attachment to host cells, fusion with the cell membrane, and entry into the host cell. They are typically made up of glycoproteins and are often responsible for eliciting an immune response in the host organism. The exact structure and function of viral envelope proteins vary between different types of viruses.
I'm sorry for any confusion, but "Sri Lanka" is not a medical term or concept. Sri Lanka is an island country located in the Indian Ocean, south of India. It is known for its diverse landscapes ranging from rainforests and arid plains to highlands and sandy beaches.

I am not aware of a specific medical definition for "Cuba." Cuba is actually a country, specifically an island nation located in the Caribbean Sea. It is south of Florida and the Bahamas, west of Haiti, and north of Jamaica. The term "Cuba" would not typically be used in a medical context unless it was referring to something or someone that is related to or originates from this country. For example, a "Cuban immigrant" might be mentioned in a medical history, or a patient might have traveled to Cuba for medical treatment. In these cases, the relevant medical information would relate to the individual's personal history or the specific medical care they received, rather than to any inherent qualities of the country itself.
I'm sorry for any confusion, but "rain" is not a medical term. In general, rain refers to water droplets that fall from the sky as part of the Earth's weather cycle. These drops form when moisture in the air condenses and cools, creating clouds which eventually become heavy enough to release the collected water.
If you have any medical concerns or questions, I'd be happy to try and help answer those for you!
An antigen is any substance that can stimulate an immune response, particularly the production of antibodies. Viral antigens are antigens that are found on or produced by viruses. They can be proteins, glycoproteins, or carbohydrates present on the surface or inside the viral particle.
Viral antigens play a crucial role in the immune system's recognition and response to viral infections. When a virus infects a host cell, it may display its antigens on the surface of the infected cell. This allows the immune system to recognize and target the infected cells for destruction, thereby limiting the spread of the virus.
Viral antigens are also important targets for vaccines. Vaccines typically work by introducing a harmless form of a viral antigen to the body, which then stimulates the production of antibodies and memory T-cells that can recognize and respond quickly and effectively to future infections with the actual virus.
It's worth noting that different types of viruses have different antigens, and these antigens can vary between strains of the same virus. This is why there are often different vaccines available for different viral diseases, and why flu vaccines need to be updated every year to account for changes in the circulating influenza virus strains.
I'm sorry for any confusion, but "Polynesia" is not a medical term. It is a geographical region in the Pacific Ocean, consisting of numerous island countries and territories. If you have any questions related to medical terminology or health, I would be happy to try and help answer those for you.
I'm sorry for any confusion, but "Singapore" is not a medical term or concept. It is a sovereign city-state and island country in Southeast Asia. If you have any questions related to medical topics or definitions, I would be happy to try and help answer those for you!
An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.
Hypotension is a medical term that refers to abnormally low blood pressure, usually defined as a systolic blood pressure less than 90 millimeters of mercury (mm Hg) or a diastolic blood pressure less than 60 mm Hg. Blood pressure is the force exerted by the blood against the walls of the blood vessels as the heart pumps blood.
Hypotension can cause symptoms such as dizziness, lightheadedness, weakness, and fainting, especially when standing up suddenly. In severe cases, hypotension can lead to shock, which is a life-threatening condition characterized by multiple organ failure due to inadequate blood flow.
Hypotension can be caused by various factors, including certain medications, medical conditions such as heart disease, endocrine disorders, and dehydration. It is important to seek medical attention if you experience symptoms of hypotension, as it can indicate an underlying health issue that requires treatment.
Fever, also known as pyrexia or febrile response, is a common medical sign characterized by an elevation in core body temperature above the normal range of 36.5-37.5°C (97.7-99.5°F) due to a dysregulation of the body's thermoregulatory system. It is often a response to an infection, inflammation, or other underlying medical conditions, and it serves as a part of the immune system's effort to combat the invading pathogens or to repair damaged tissues.
Fevers can be classified based on their magnitude:
* Low-grade fever: 37.5-38°C (99.5-100.4°F)
* Moderate fever: 38-39°C (100.4-102.2°F)
* High-grade or severe fever: above 39°C (102.2°F)
It is important to note that a single elevated temperature reading does not necessarily indicate the presence of a fever, as body temperature can fluctuate throughout the day and can be influenced by various factors such as physical activity, environmental conditions, and the menstrual cycle in females. The diagnosis of fever typically requires the confirmation of an elevated core body temperature on at least two occasions or a consistently high temperature over a period of time.
While fevers are generally considered beneficial in fighting off infections and promoting recovery, extremely high temperatures or prolonged febrile states may necessitate medical intervention to prevent potential complications such as dehydration, seizures, or damage to vital organs.
